*Magnetic saturation generator design, 20years designed life.(Patent No.:ZL 2007 2 0010261.7)
*2-2.5m/s start-up wind speed under low torque start-up technique.(Patent No.:201020259728.3)
Mechanical automatic yawing.
*Matched controller with constant voltage charging, electronic and manual brake, and numeral panel display.(Patent No.:200910213782.6)
*500W, 600W and 1KW blades are cast into molding at one time with balance up to 99%.
*Bearings import from Japan (NSK), long service time (5 years maintenance-free).
*Magnetic saturation design, the generator coil couldn’t burn down because of the increasing power, when generator runs at a super wind speed and saturates automatically.
*Low cut in wind speed (3m/s) to guarantee the maximum generation at low wind speed.
